Chapter 3: Lumps, Bleeding, and Persistent Pain

Not every oral health problem causes an obvious sore.

Sometimes the first noticeable change is a lump, thickened area, swelling, or persistent tenderness.

A lump in the mouth can develop for many reasons. It may be associated with a blocked salivary gland, infection, trauma, cyst, benign growth, or another dental problem.

In some cases, however, persistent oral lumps can be associated with cancer.

The important distinction is not simply whether a lump exists, but how it behaves.

A new area that continues to enlarge, becomes firm, repeatedly bleeds, or does not resolve should be examined.

Unexplained bleeding is another symptom worth taking seriously.

Gums can bleed because of gingivitis, periodontal disease, aggressive brushing, certain medications, or other common causes. Therefore, occasional bleeding does not automatically indicate something dangerous.

But bleeding from a particular lesion, especially when it happens repeatedly without an obvious explanation, deserves professional attention.

Persistent pain or numbness can also be significant.

Some people expect serious conditions to cause severe pain immediately. That isn't necessarily the case. Certain oral cancers may initially cause little or no pain.

A person might instead notice a strange sensation, persistent tenderness, numbness of the lip or tongue, or an area that simply feels different.

Difficulty chewing or swallowing is another symptom that should not be ignored when it persists.

Some people may notice that food seems difficult to move through the mouth or throat, while others experience discomfort when swallowing. Again, these symptoms can result from many non-cancerous conditions, including infections, reflux, dental problems, and neurological or muscular disorders.

Changes in speech can also occur when a persistent lesion affects the tongue, mouth, or throat.

None of these symptoms provides enough information to diagnose cancer.

Their importance comes from persistence, unexplained progression, and combinations of symptoms.
